Rachel Dolezal stepped down from her position as the president of an NAACP chapter in Washington State on Monday – days after her ethnic identity became a national controversy.

The civil rights activist made the announcement in an open letter – posted on Facebook – to the organization’s executive committee and members.

“It is with complete allegiance to the cause of racial and social justice and the NAACP that I step aside from the Presidency and pass the baton to my Vice President, Naima Quarles-Burnley,” she wrote.

Dolezal vowed to always fight for “what is right and good in this world” and thanked everyone who had supported her throughout the media firestorm that erupted over her ethnicity.
